Choriocarcinoma is the most malignant tumor of gestational trophoblastic neoplasia. Choriocarcinoma presenting as postpartum hemorrhage and spontaneous uterine perforation with intra-abdominal hemorrhage is very rare. We present a 29-year-old woman with spontaneous uterine rupture due to choriocarcinoma following a live birth pregnancy.
